Anyone have an idea what this may be?

Stereo power amp. The wirewound emitter resistors for a complementary output stage gives it away, as well as the output inductor networks. You can also see the complementary (heatsinked) driver transistors.

Oops, I only clicked on the first picture; looking at the last one I agree this is likely an audio amplifier. No doubt a totem-pole output stage with truly atrocious distortion, too.

I'd go with audio amp myself as well. My father built one almost identical other than enclosure and mounting. It sounded like ass.
